Project description
In 2011, the Bill & Melinda Gates Foundation announced a research and innovation challenge aimed at concept development, design, and prototyping of sustainable and low-cost sanitation systems. With 2.6 billion people still lacking access to improved sanitation, the BMGF sought to produce a new-generation self-sustaining toilet that converts human waste into usable resources, and that minimizes the amounts of clean water and energy used in the system. The toilet will be off-the-grid, doing away with the need for a connection to large electricity, water or sewerage networks. Affordability is a key goal of the RTTC, with a target combined capital and operating cost for the toilet of less than 10 US cents per person per day.
